1. High-Wear Cutting & Shaping Tools
These are the "business end" of the machine and require the most frequent replacement or sharpening.
Nail Cutters (Dies): Used to cut the wire and form the point of the nail. Usually made of tungsten carbide for longevity.
Grip Dies (Clamping Dies): These hold the wire firmly in place while the head is being formed.
Header Punch (Hammer): The part that strikes the end of the wire to form the nail head.
2. Feeding & Straightening Components
If these wear out, your nails will come out crooked or vary in length.
Straightening Rollers: A series of wheels that remove the coil memory from the wire.
Feeding Rollers/Wheels: These pull the wire into the machine at precise increments.
Feeding Pawls: Small mechanical "fingers" that push the wire forward in older mechanical models.
3. Mechanical Drive & Transmission
V-Belts: Standard power transmission belts that can fray or snap over time.
Crankshaft Bushings & Bearings: Critical for reducing friction in the high-speed reciprocating parts.
Tension Springs: Used to return cutters and grippers to their original positions.
Maintenance Pro-Tip
| Part | Material Type | Average Life |
| Cutters | Tungsten Carbide | 1–3 Months (can be reground) |
| Grip Dies | Alloy Steel / Carbide | 2–4 Months |
| Punch | High-Speed Steel | 1–2 Months |
